I have been trying out Cargo with Houdini 19 (and 20) and it seems that the Materials are coming in with the wrong settings. When compared with the download kits, I have found that the following is causing display problems. The transparency channel (when needed) is not set to 1 but left at zero. The base colour is almost black and going by the download kits it should be closer to white. Currently this means that I have to change all the material settings in order to get the image to render like the views in the Cargo Application
